COPD is a preventable and treatable chronic airway disease characterized by persistent airflow restriction, mainly developed from chronic bronchitis and emphysema, which accounts for 8.2% of the population over 40 years of age in China, with about 2.5 deaths per minute. COPD is also known as the “silent killer”, and is complicated by chronic respiratory failure and pulmonary heart disease in the late stage, and is clinically divided into acute exacerbation and stable stage. In the early stage, the main manifestations are loss of lung qi; in the middle stage, lung qi deficiency or deficiency of both lung and spleen; in the late stage, deficiency of both lung and kidney. Risk factors: include both individual susceptibility factors and environmental factors, which interact with each other Individual susceptibility factors such as alpha1-antitrypsin deficiency as a known genetic factor, bronchial asthma and airway hyperresponsiveness are also risk factors for COPD Environmental factors such as smoking (the main risk factor), occupational dust and chemicals, air pollution, and infections (including previous tuberculosis). Treatment Acute exacerbation: Get to the hospital without delay. Stable phase: recommended treatment regimen Grading Characteristics Recommended treatment regimen Grade I (mild) FEV1/FVC < 70%, FEV1 Avoid risk factors; vaccination against influenza; ≥ 80% of expected value Use short-acting bronchodilators as needed Grade II (moderate) FEV1/FVC < 70%, 50% ≤ FEV1 On the basis of treatment in the previous - grade Regular application of one or more long-acting bronchodilators < 80% of expected value, rehabilitation Grade III (severe) FEV1/FVC < 70%, 30% ≤ FEV1 Recurrent acute exacerbations on the basis of the previous level of treatment, < 50% of expected value Inhaled glucocorticoids or roflumilast (PDE-4 inhibitor) IV (very severe) FEV1/FVC < 70%, FEV1 on the basis of the previous level of treatment On the basis of the previous level of treatment, if there is respiratory failure <30% of the expected value, or <50% with long-term oxygen therapy, surgical treatment may be considered, requiring chronic respiratory failure. Our hospital features Treating the disease before it occurs (join the club, experts are always at your service) 1.Preventing the disease before it occurs - stop smoking, prevent respiratory infections and the above risk factors, and prevent the occurrence of COPD 2.Preventing the disease before it occurs - early diagnosis and treatment to prevent the development and transformation of COPD Long-term smokers or those older than 40 years old, or those with the above risk factors or those who often cough and sputum or feel shortness of breath and chest tightness, have a lung function test! 3.Prevent COPD relapse after kilograms--Prevent COPD relapse by using pulmonary rehabilitation therapy (breathing exercises, walking, Tai Chi, etc.), acupuncture, acupuncture point therapy (including acupuncture point buried thread), foot bath, medicinal food, dietary therapy and Chinese medicine evidence-based treatment, as well as strengthening nutritional and metabolic support and respiratory muscle function exercise.
